The 2017 WHO classification and International Classification of Disease coding analysis of non⁃neuroendocrine tumors in the pituitary gland

Abstract

The fourth edition of the latest classification principles for endocrine tumors was published by the World Health Organization (WHO) in 2017. The latest tumor classification and new pathological classification of each pituitary gland tumor were given in detail. In May 2021, International Classification of Disease⁃11 (ICD⁃11) was updated and the independent additional code of each type of tumor was enriched. Non⁃neuroendocrine tumors, including craniopharyngioma, neuronal and paraneuronal tumors, tumors of posterior pituitary, mesenchymal and stromal tumors, hematolymphoid tumors, germ cell tumors, and secondary tumors in the pituitary gland are described. The corresponding disease codes and morphological codes are listed in combination with ICD⁃10, ICD⁃11 and ICD⁃O. Detailed additional codes for each tumor are listed according to ICD⁃11.
